Characteristics of films obtained from fish myofibrillar proteins extracted from various solubilization methods were investigated. In this study, we utilized three agents to solubilize fish myofibrillar proteins from surimi, which are sodium chloride, sodium tripolyphosphate, and alkaline condition. The first part of this study focused on combination of sodium chloride...
The ability of salmon plasma protein (SPP) obtained from Chinook salmon at the Klaskanine Fish Hatchery (Astoria, OR) to inhibit protease enzymes found in Pacific whiting (PW) surimi and salmon mince as well as the effect of SPP on the gelation properties of PW surimi under various heating conditions was...
Rice flour possesses functional properties in enhancing texture and whiteness. This study was carried out to evaluate rice flour as a functional ingredient for premium crabstick and to develop a commercially viable recipe for premium crabstick. Crabstick pastes were formulated with constant surimi (42%) and combined rice flour and starch...
The major portion of Pacific whiting (PW) is commercialized in the form of frozen surimi. Alternative products for PW were investigated focusing on fresh surimi and texturized meat from PW mince. Fresh surimi is made without additives and kept refrigerated instead of frozen. Texturized meat is a meat-like product made...
The effects of the residual salt of surimi on biochemical and physical properties as affected by various freeze and thaw cycles were examined. Fresh Alaska pollock (Theragra chalcogramma) surimi was mixed with 4.0% sugar, and 5.0% sorbitol, along with eight combinations of salt (0.4, 0.6, 0.8, and 1.0 % NaCl)...
A novel method for isolating fish proteins by shifting pH to high acid or high alkali pH was the focus of the study. Biochemical and physicochemical properties of various pH-treated soluble fish proteins as a function of ionic strength were determined. Effect of ionic strength and various storage conditions on...
Optimization of comminuting and heating conditions for surimi gel preparation obtained from three fish species: Alaska pollock (AP) (Theragra chalcogramma), Pacific whiting (PW) (Merluccius productus), and threadfin bream (TB) (Nemipterus spp.) was the focus of this study. Three parameters during comminution were separately evaluated: chopping time, chopping temperature, and salting...
There are presently two successful methods used to refine fish muscle proteins: surimi and fish protein isolate (FPI). Both surimi and FPI have the ability to form an elastic gel upon comminution and heating. However, their gelation behaviors are different as they are refined in a biochemically opposite way based...
Gadoid fish, like Alaska pollock and Pacific whiting, have a high level of trimethylamine-N-oxide demethylase (TMAOase) that catalyzes the breakdown of trimethylamine-N-oxide (TMAO) to formaldehyde (FA) and dimethylamine (DMA) even during frozen storage. FA reacts with amino acid residues to promote covalent cross-links in the formation of inter- and intramolecular...
